An article appearing 25 Feb 1923 in the Italian paper Domenicia del Corrier pictured alleged new issues from Azerbaijan. A local, unscrupulous firm of
printers seized upon the opportunity and produced these "new issues" for the far-away land. There are six values as shown above and they exist both
perf 11 1/2 and imperforate. The originals have diagonally crackling gum.
Now the forgers went to work and produced a set perf 11 with smooth gum, a coarser lithograph and design size differences. A second set of forgeries
exist both perf 11 1/2 and imperforate, also with smooth gum, coarser lithograph and design size differences.
